The concept and characteristics of the ecotype supply chain are discussed in the paper firstly, and then a further improvement of performance evaluation index system of ecotype supply chain is made. Based on the above discussion, a fuzzy BP neural network evaluation method which optimized by PSO is established. Through an example, the proposed method is used to evaluate the performance of an ecotype supply chain according to the evaluation criteria, which offers effective decision-making approach for the sustainable development of the enterprises in the future market competition.
